·Only connect strings at one input zone and never mix
the input zones 1 and 2!
For instance, if the positive pole of a string is

The inverter may only be operated with PV generators
(Class A PV modules according to IEC 61730 and
cabling) of protection class II. Do not connect any
sources of energy other than PV modules to the inverter.

For Sununo – TL 1.5K/2K/3KB/4KB, there is just one MPP Tracker. These
single MPPT inverters require same type module same quantity, identical
alignment and tilt.
For Sununo–TL3KA/4KA/5K,SU3KMTLI/SU4KMTLI/SU5KMTLI, there are
two MPP Trackers for the two string inputs. Unlike the traditional single MPPT
inverters which require same type module, same quantity, identical alignment
and tilt, the multi-MPPT SAJ grid-tie inverters can deal with different solar
modules, different quantity, different alignment and tilt, thus can withstand
harshest environmental conditions.
